Phone Overview
The Cisco IP Phones 8800 Series provides voice communication over an Internet Protocol (IP) network. The
Cisco IP Phone functions much like any digital business phone, allowing you to make phone calls and to
access features such as mute, hold, transfer, and more. In addition, because the phone connects to your data
network, it offers enhanced IP telephony features, including access to network information and services, and
customizable features and services.
The Cisco IP Phone 8811 has a grayscale LCD screen. The Cisco IP Phones 8841, 8845, 8851, 8851NR, 8861,
8865, and 8865NR have a 24-bit color LCD screen.
When adding features to the phone line keys, you are limited by the number of line keys available. You cannot
add more features than the number of line keys on your phone.
The Cisco IP Phones have the following features:
•
Programmable feature buttons that support up to 5 lines in Session Line Mode or up to 10 lines with
Enhanced Line Mode
•
Full video capabilities (Cisco IP Phones 8845, 8865, and 8865NR only)
•
Gigabit Ethernet connectivity
•
Bluetooth support for wireless headsets (Cisco IP Phone 8845, 8851, 8861, and 8865 only. This feature
is not supported on Cisco IP Phone 8811, 8841, 8851NR, and 8865NR.)
